How do i clear the voice mail on my land line phone?

To clear the voicemail on your landline phone, pick up the handset and dial your voicemail access number, which is usually your own phone number or a specific code provided by your phone service provider. Follow the prompts to listen to your messages, and when prompted, you can delete messages you no longer want. If you want to clear all messages, there may be an option for that as well. Finally, hang up the phone to complete the process.
